What are the general properties of packaging film?


1. Unitization: This is one of the great characteristics of packaging film. With the strong winding force and retraction of the film, the product is compactly and fixedly bundled into a unit, so that the scattered small pieces become a whole, even in the adverse environment, the product is not loose and separated, and there is no sharpness. Edge and stickiness to avoid damage.
2. Initial protection: The initial protection provides the surface protection of the product, forming a very light and protective appearance around the product, so as to achieve the purpose of dustproof, oilproof, moistureproof, waterproof and anti-theft. It is especially important to make the packaged items evenly stressed to avoid damage to the items due to uneven force, which is not possible with traditional packaging methods (bundling, packing, tape, etc.).
3. Compression fixity: The product is packaged with the help of the retraction force of the packaging film after stretching to form a compact unit that does not occupy space, so that the pallets of the product are tightly wrapped together, which can avoid product damage during transportation. Mutual displacement and movement, and at the same time, the adjustable stretching force can make the hard products tightly close, and make the soft products shrink, especially in the tobacco industry and the textile industry with specific packaging effects.
4. Cost saving: the use of packaging film for product packaging can reduce the cost of use. It is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, increase packaging efficiency and packaging quality.
